Neck and back: what is connected to the jaw, and what is not.

You go to physiotherapy, osteopathy or massage regularly, it feels good, and after a short time the tension is back. On this page we explain where the jaw system can play a role and where we have to say honestly: that is not proven.

The cervical spine and the jaw system: close neighbours

The cervical spine and the jaw system are controlled by shared reflexes. Both are connected via the same nuclei in the brainstem, and the deep neck muscles are in close contact with the jaw and head-holding muscles through connective tissue. That is why tension in one area affects the other, in both directions. People who grind a lot often feel it in the neck; people with a stiff cervical spine often bite differently.

This connection between the jaw system and the upper cervical spine is well understood and widely recognised. Examining and treating the cervical spine as well is standard practice in CMD, not as an add-on, but because the two belong together.

Typical complaints

  • Chronic tension in the neck and shoulder area, often more pronounced on one side.
  • Restricted movement when turning the head, most noticeable in the morning.
  • Tender points at the base of the skull and on the shoulder blade.
  • A headache that spreads from the neck to the front.
  • A feeling of being lopsided: head held slightly to one side, one shoulder higher.
  • Tension that eases after treatment and keeps returning.

What is established, and what is not. To be honest: For the head, face and upper cervical spine the connection with the jaw system is well researched and understood; treating the cervical spine as well is standard practice. For the spine as a whole, the pelvis and the feet it looks different: here the evidence is inconsistent, and a causal link with the bite position is not proven. What we observe in practice is clinical experience, not established evidence. We prefer to tell you this beforehand rather than promise you something the data do not support.

How the connection is thought to work

Three levels are described in the literature:

  • Muscular and fascial connections. The jaw muscles and the head-holding and neck muscles are connected by connective tissue; tension is transmitted along these chains.
  • Reflex control. The cervical spine and the jaw system are controlled by shared reflexes. This is the best supported of the three levels.
  • Body posture. In our clinical experience, an unfavourable bite position can encourage compensatory postures. How far this extends beyond the neck is scientifically open, so we present it as an observation, not as a mechanism.

Physiotherapy stays, and we work with it

Physiotherapy, manual therapy, osteopathy, chiropractic and orthopaedics are the guideline-based first line for neck and back complaints. They are effective, well researched and valuable partners for us. If you are being treated there: please carry on.

Our contribution is a different and complementary one. We check the part of this chain that usually nobody measures: how the jaw system works. The CMD System Check measures, among other things, how hard your masticatory muscles work, with what force your teeth meet and how your lower jaw moves. If nothing unusual shows up, we tell you just as clearly. Then the cause lies elsewhere, and you have one possibility fewer to consider.

You can take the first step in two minutes with the CMD self-test.

See a doctor first

When you need to see a doctor first. You need an immediate medical assessment, not CMD diagnostics:

  • With numbness or tingling in the arm, hand or leg
  • With loss of strength
  • With complaints after a fall or accident
  • With bladder or bowel problems
  • With fever or unintended weight loss
  • This is not a formality; it is the point where order matters.

Frequently asked questions

Frequently asked questions

Your question is not here? Ask us directly.

Should I continue my physiotherapy?

Definitely. Physiotherapy, manual therapy and osteopathy are the guideline-based first line for neck and back complaints and complement CMD treatment. We are happy to work with the professionals you already see.

Can neck pain really come from the jaw?

For the upper cervical spine, the connection is well understood: the jaw system and the cervical spine are controlled by shared reflexes and closely linked through muscles. Whether this plays a role for you can only be clarified with an examination, not deduced from the complaint.

Are the back, pelvis and feet also connected to the bite?

This is often claimed, and we observe connections in practice. Scientifically, however, the picture for the spine, pelvis and feet is inconsistent; a causal link is not proven. We say this openly rather than turning it into a treatment promise.

When should neck complaints go to a doctor first?

With numbness or tingling in the arm, hand or leg, loss of strength, after a fall or accident, with bladder or bowel problems, fever or unintended weight loss: see a doctor immediately.

Does the jaw system play a role for you?

No obligation, with an immediate first assessment.
